In acentral-draftlam p, the combination, with the central drafttuhe,of a flamespreader, removably connected with the upper end of said tube, provided with a tube connected therewith and extending through its top or cap piece, the upper projecting end of said tube being adapted for the detachable connection therewith of a burner.

3. In a central-draft lamp, the combination,

with the central draft tube, of a flamespreader, removably connected with the upper end of the tube, provided with a vertically-arranged tube extending through its top or cap piece and being rigidly connected therewith, the opposite ends of said tube being adapted for the detachable connection therewith of a burner and gas-tube respectively. 4E. A flame-spreader for central-draft oillamps, provided with a tube connected therewith and extending through one wall thereof, the exterior projecting end of said tube being adapted for the detachable connection therewith of a burner.

5. A dame-spreader for central-draft oillamps, provided with an opening extending therethrough and having means adjacent to the upper end of said opening for the connection therewith of a burner, for the purpose set forth.

G. A centraldraft oil-lamp provided with a central draft-tube having a cap or device adjacent toits upper end which is provided with an opening extending therethrough and with means adjacent to the upper end of said opening for the connection therewith of a burner, for the purpose set forth.
